Research On Micro-payment Based On P2P

With the rapid development of Internet, the P2P network technology becomes more and more mature. In P2P network, a node can be regarded as a server or client, that is to say, a node can both provide and obtain resource and service. Meanwhile,the globalization of e-commerce activities to promote the rapid development of e-commerce core areas,which is also called electronic development. According to the amounts paid, Electronic payment is divided into macro-payment and micro-payment. Micro-payment is drawing attention of experts and scholars for its small volume of transactions, large number of transactions, rapid transaction speed and other characteristics,as well as the application is different from the macro-payment.Taking the digital good transactions in P2P network as study object, this thesis focuses on the research of micro-payment in P2P network. The thesis mainly includes the following three aspects:1.The thesis will analyze several typical micro-payment agreements in P2P internet environment on the basis of systematically studying the basic model, the business process and the relative knowledge of cryptography. It provides the theoretical and practical basis for the following research.2. Proposed a new P2P micro-payment protocol based on BA(Brokers Assistant), the contribution of the protocol is mainly due to:Sloved the problem of broker,who’s burden too heavy, when business is not noline. Meanwhile, it can find out the double spending of the business and customer in time by payment word chain. In the agreement, the node adapts anonymous identification to protect the privacy security of a node effectively; Proposed a selection mechanism,which can effectively reduce the information retrieval in the P2P network delay,based on the regional division of the QQIP address database to build the Broker Assistant.3. Simulation of the new protocol, The results of reasearch show that:with the increase in the number of nodes in the P2P network, P2P-BAPay’s performance will be higher than the P2P the-NetPay and PPay.4.According to micro-payment protocol of P2P-BAPay, the author developed a simple simulation of micro-payment system, it realizated the basic core functionality of micro-payment.
